The CS51021A/2A/3A/4A Fixed
Frequency PWM Current Mode
Controller family provides all neces-
sary features required for AC-DC or
DC-DC primary side control.
Several features are included elimi-
nating the additional components
needed to implement them external-
ly. In addition to low start-up cur-
rent (75A) and high frequency
operation capability, the
CS51021A/2A/3A/4A family
includes overvoltage and undervolt-
age monitoring, externally pro-
grammable dual threshold overcur-
rent protection, current sense lead-
ing edge blanking, current slope
compensation, accurate duty cycle
control and an externally available
5V reference. The CS51021A and
CS51023A feature bidirectional syn-
chronization capability, while the
CS51022A and CS51024A offer a
sleep mode with 100A maximum
IC current consumption. The
CS51021A/2A/3A/4A family is
available in a 16 lead narrow body
SO package.
